Will 370z pistons work in a 350Z?

Like the heading say, will it work. I see the diameter is the same.

Please say why? I don't think it's up to you to say when a thread is over.

I was just kinda joking. Different displacement with the same Amount of cylinders means that they have to be a different size.

Only if the stroke remains the same. ;)

The 3.5 L (3,498 cc) VQ35DE is used in many modern Nissan vehicles. Bore and stroke are 95.5 mm and 81.4 mm.

It was the first production engine from Nissan using VVEL. It has an increased compression ratio of 11.0:1, with 3,696 cc (225.5 cu in) displacement (95.5 mm bore and 86 mm stroke),

I wouldnt use the VHR piston in the HR engine for sure because the VHR doesnt have valve relief for the exhaust valve.
as far as the DE engine, it should be pretty much the same story.

but I did the swap of the VHR crank/connecting rod + HR piston in my spare HR engine.
I had to machine some spot on those pistons to have enough clearance.
